Well, I just wished to warn that the dependency of kdegames4 on OpenAL
and any problems arising will increase as more games start to use it.

But I do not understand why pulling in a library from outside Macports is necessarily
an issue.  Sound (with OpenAL) is working for me in KGoldrunner.  I did:

Tara:~>port search openal
openal @1.3 (audio, devel)
    OpenAL is a cross-platform 3D audio API
Tara:~>port installed | grep openal
Tara:~>port installed | grep kdegames
  kdegames4 @4.7.4_0
  kdegames4 @4.8.1_0 (active)

So it seems sounds in kdegames4 are OK for me but I am not getting OpenAL
from Macports.  I am using Mac OS X Lion 10.7.2 and Macports 2.0.4.
